Taller design could mean this is the ZenFone Max 5, with the extra height necessary for the phone’s larger battery.

Vertical dual-camera and rear fingerprint sensor also shown off ahead of the device’s expected reveal at MWC 2018.

Asus looks set to stroll into MWC 2018 with a handful of devices that succeed the ZenFone 4 range. Just last week we saw a ZenFone 5 phone rear its head in a Wi-Fi Alliance listing. Thanks to a newly leaked image, we now have a good idea what one of the 5-series devices will look like.

The diagram we’re looking at is apparently taken directly from an official manual and depicts a phone only referred to as the “Asus X00PD”. Based on the device’s height, which may have been extended to fit a larger battery, the folks over at WinFuture believe this is the ZenFone 5 Max.

Asus ZenFone Max Plus hands-on

Asus is one of the stranger companies when it comes to mobile devices. They often try to make super affordable handsets with incredibly competitive specs, but they don't go out of their way to try …

As well as enough room to house a chunky battery that potentially outdoes its predecessor, the image also appears to confirm that the ZenFone 5 Max, and most likely every ZenFone 5 device, will sport an elongated 18:9 aspect ratio display.

To make way for the estimated 5.7-inch screen, Asus has apparently shifted the fingerprint sensor to the handset’s rear – right next to a dual-camera unit with a vertical orientation that looks a lot like a certain iOS phone. There’s also a traditional 3.5mm jack for those that haven’t swapped over to wireless headphones just yet.

While the overall design looks neat enough for a possible mid-to-low-range device with a monster battery, there are a few quirks that hopefully don’t transfer over to the rest of the ZenFone 5 family.

The most notable is the device’s MicroUSB port instead of USB-C. Dual-sim and/or microSD card support also appears to be off the table. ZenFone 5 leaks allegedly showing non-Max models have previously shown these features for other models, but we’ll have to wait for official confirmation to be sure.

Spec-wise we’re also a bit in the dark. There have been several benchmark reports doing the rounds with the X00PD model number that list Qualcomm’s Snapdragon 430 SoC, but RAM, storage, and the phone’s all-important battery capacity rating are still unknown. On the plus side, every ZenFone 5-related leak has hinted that each device will be powered by Android 8.0 Oreo out-of-the-box.

Considering that the ZenFone 4 series only launched in the US just a few months ago, it could be a fair while before the ZenFone 5 family makes its debut in the region. We’ll no doubt hear a little more at MWC, and Android Authority will be there bringing you the news live from the show.
